CCWDM Mux Demux, Single Fiber 2/4/8/9 Channels, TX RX, Optional Connectors and Housing

Compact coarse wavelength division multiplexers (CCWDM Mux) is the mini version of CWDM Mux. Compared with traditional CWDM technology, CCWDM technology uses free-space optics platform which can significantly improve optical performance, in a package less than 1/4 the size of conventional CWDM modules. Main advantages of CCWDM Mux are high wavelength accuracy and stability, low insertion loss, high isolation and low PDL(polarization dependent loss). It's protocol and rates transparent supporting such applications as the CWDM system, PON networks, and CATV Links.

Unique Free-Space Technology

The CCWDM Mux adopts Free-Space technology, which uses light propagating in free space to wirelessly transmit data. Inside the device, adjacent signal channels are cascaded by parallel beam instead of the fiber. This saves a lot of space for package box, and the unique workmanship also helps CCWDM Mux Demux with low insertion loss.

Comparison between CCWDM and CWDM

Insertion Loss <2.6 dB

The insertion loss of CCWDM Mux is about half of the conventional CWDM Mux. This reduces the overall loss of the whole link, and leaves more choices for the design of the solution.

Compact Package Design

CCWDM Mux uses the parallel beam for cascading instead of the fiber, which saves significant space. The minimum dimension of CCWDM aluminum box module is less than the 1/4 size of minimum CWDM ABS pigtailed module.

Structure and Dimension

The aluminum box of single fiber CCWDM Mux Demux has 2 kinds of dimension. For the 4 channels CCWDM Mux, the dimension is 44mm(W)*25mm(D)*6mm(H), and for the 8 channels CCWDM Mux, the dimension is 55mm(W)*45mm(D)*6mm(H).
